couple of wiring questions OBC and cruise

[jimbom30cab]

On the 13OBC there is a white plug with a green and a green with red stripe. Can't find out where it connects to

My Cruise has a brown wire right by the earth blot behind the glove box but the brown wire has a connector plug on it, I was expecting a round thingy to fit over the earth bolt, it's more like an accessory socket female connector

On th cruise there is a thin blue wire, i'm assuming this is only needed for an auto car.

On the 13OBC there is a little male plug right near the OBC disply, single wire looks organge ??

THANKS

My car is 1987 325i manual RHD.

Checking out the Wiki, as I don't have an immobiliser I think i need to join the green wires together.

Green and green/red plug into the immobiliser socket, above the glovebox area. This will already be occupied by a plug with a short loop of green wire, or by a correctly fitted immobiliser plug.
Don't have my big book of E30 knowledge handy, but plain brown is always earth, plain blue is probably road speed (from the back of the instrument cluster), and, I'm fairly sure there is an unused single plug on the OBC loom, near where you say.
